Signing Android apps

After reading android developer official guide Signing Your Applications I was a little bit confused what exactly I have to do for signing app.
Basically process of signing apps includes five steps:

1. Create your keystore;
2. Prepare app for signing (removing logs, increment version etc);
3. Export app as unsigned apk;
4. Sign apk;
5. Run zipalign tool.

There are three ways:

1. Do it manually from command line;
2. Use ANT script;
3. Do it with the help of wizard in Eclipse.

Eclipse wizard will do 3-5 steps automatically.

So the fastest way to sign apk is to:

1. Create your keystore;
2. Prepare app for signing (removing logs, increment version etc);
3. Export signed apk with Eclipse.

Create keystore

$ keytool -genkey -v -keystore APPNAME.key -alias APPNAME -keyalg RSA -keysize 2048 -validity 10000

Check if JAVA_HOME is set or find keytool executable file in bin folder of Java.


Show keystore info

$ keytool -list -v -keystore afit.key

Export signed apk with Eclipse

Right click on project > Android Tools > Export Signed Application Package... > and follow wizards instructions.
